GILD verdict
Pick kcap to keep coding agents' sessions as searchable team memory priced per seat, and Braintrust to score and test an AI application you build.
For a team of 10 on monthly billing, GILD's calculation puts kcap Team at US$225 a month from the pricing page against US$0 on Braintrust Starter within its included data and scores, before token rates.
Disclosure: Kurrent is a GILD event partner. GILD writes its reviews on its own. kcap records every coding agent's sessions as shared team memory, priced per seat. Braintrust measures AI application quality with offline experiments and online scoring, and its trace-claude-code plugin records Claude Code sessions as spans, on plans priced by processed data and scores.
Choosing between kcap and Braintrust
Choose kcap if
- Your team runs several coding agents and wants every session searchable by teammates and readable by the next agent.
- You want seat pricing, with a free local edition for one developer.
- Agents should search past sessions through MCP tools that respect each user's session visibility.
Choose Braintrust if
- You score and test an AI application your team builds and want regressions caught before they reach production.
- Claude Code should query logs, compare experiments and work with datasets through the Braintrust MCP.
- You need on-prem or hosted deployment, which Braintrust offers on Enterprise.
Side by side
| Dimension | kcap | Braintrust |
|---|---|---|
| Session capture | A hook in each coding agent sends the session to the workspace as it happens: prompts, the agent's replies, every tool call and its result, and the commits it made1 | For Claude Code with the trace-claude-code plugin, Braintrust records session, turn, model call, tool and subagent spans7 |

| Monthly list price for a team of 10 developers (GILD calculation)GILD calculation from Kurrent's pricing page and llms.txt and Braintrust's pricing page on Nov 4, 2026. Inputs: 10 developers with one kcap seat each, monthly billing for the pricing page's figure and for llms.txt's US$180 figure, annual billing for llms.txt's US$150 figure, and Braintrust usage within each plan's included data and scores. Kurrent's two pages disagree, so the kcap cell gives both. | For a team of 10 developers on Team: US$225 a month, US$100 for the first five seats plus 5 times US$25, from the pricing page's structured data. At llms.txt's per-person price, US$150 a month billed annually or US$180 billed monthly23 | For a team of 10 developers: US$0 a month on Starter while the team's traces stay within 1 GB of processed data and 10k scores, before token rates, or US$249 a month on Pro within 5 GB and 50k scores8 |
| Retention | Sessions are retained until deleted: a member can delete their own sessions and an admin can delete any session4 | Starter has 14-day retention, and Pro has 30-day retention plus US$0.50/GB/mo8 |
| Search and agent accesskcap searches coding-agent sessions, and Braintrust's MCP queries logs and experiments. | The kcap-sessions MCP server lists search_sessions, list_repo_sessions, list_turns and get_turn, and reads are filtered by the user's session visibility5 | With the Braintrust MCP connected, Claude Code can query logs, compare experiments, work with datasets and use other Braintrust tools7 |
| Where it runs | A cloud workspace is hosted in the EU on infrastructure Kurrent operates, and the local edition runs on the user's machine4 | The Enterprise plan offers on-prem or hosted deployment, and the Claude Code page lists US and EU data planes and self-hosted deployments78 |
| Evaluations | Every evaluation asks the questions in the workspace's catalog, with a judge model set per vendor (defaults include claude-sonnet-4-6 and gpt-5-mini)6 | Offline experiments and online scoring to measure AI application quality and detect regressions before they reach production9 |
| Choose it if | Choose kcap if your team wants every coding agent's sessions kept as shared memory that teammates search and the next agent reads12 | Choose Braintrust if you score and test an AI application you build and want regressions caught before release89 |
